The Gaia spacecraft as seen today as a mag 15 object – after changing again the Sun aspect angle of the satellite to 0 deg earlier today – during the first hour of observations with the TFRM telescope at the Observatori Astronòmic del Montsec (OAdM) in Catalonia. A second telescope, the Telescopi Joan Oró (TJO), is observing Gaia, too. Photometric time series are taken for several hours.
